280 could mean 10 lunar months, defined as nights when Moon potentially is visible. Furtermore, the total number of glyphs in the G text (472) can then be counted as 280 + 192, which last number surely is significant, maybe because it is close to 13 / 2 * 29.5 = 191¾ or half a cycle of 13 lunar months. 176 + 16 = 192. And in Ga1-16 we can regard 11 * 6 = 66 as a hint for the location of Gb3-5 (which is number 66 on side b).

Gb3-5 is probably located at the beginning of winter (the season of takaure):


Gb3-1	Gb3-2

Gb3-3	Gb3-4 (295)	Gb3-5	Gb3-6

Gb3-7	Gb3-8	Gb3-9 (300)	Gb3-10

Gb3-11	Gb3-12	Gb3-13	Gb3-14

Gb3-15	Gb3-16

A better way to present the structure should be to begin with Gb3-5:

	176	16		213	65
Gb3-5 (296)			Ga1-16
*177 = 6 29.5**		*295 = 10 29.5**

From Gb3-5 to the end of the back side there are 177 nights, 6 lunar months, and between Gb3-5 and Ga1-16 there are 176 + 16 = 192 nights. However, to count between glyphs is not according to normal rongorongo rules (and neither is it so to count from a glyph up to and including another glyph, as when we reached 280 in the earlier table above).

Instead, we should rather count from Gb3-5 to Ga1-15:

	176	15			213	65
Gb3-5 (296)			Ga1-15	Ga1-16
192			280

Tapa mea (red cloth) in Ga1-15 presumably indicats the light from Sun (in contrast to the hau tea light from Moon). It is a day of Mercury, where a new season should begin, and this way of looking at the structure also separates in a beautiful way 3 initiary glyphs (which should not be counted when we are going for 280):

Ga1-11


Ga1-12	Ga1-13	Ga1-14


Ga1-15	Ga1-16

If Ga1-12--14 should correspond to Nga Kope Ririva, the first kuhane station (and not to be counted), then the oval form of Ga1-16 could allude to a manu tara egg. The full moon oval of Ca7-24 could also be interpreted in such a way:


Ca7-24	Ga1-16

At the apex of the Taranaki storehouse there is an egg:

But the egg of Ga1-16 is hardly positioned at the apex of a year of light. And there are no eyes visible on the creature inside.
